Problem Note 65947: A FedSQL procedure hash join incorrectly returns zero rows in SAS® Cloud Analytic Services (CAS)
 |  |  |  |  |
In CAS, a PROC FedSQL hash join that joins a CAS view with an in-line view incorrectly returns zero rows.
Here is an example of a join that would trigger the issue:
data mycas.x;
x='abcdefghijklmnopqrstuvwxyz';
run;
x='abcdefghijklmnopqrstuvwxyz';
run;
* Create a CAS view against the table. ;
proc cas;
view name='v' tables={{name='x'}};
quit;
proc cas;
view name='v' tables={{name='x'}};
quit;
* Join the view with a subquery that produces an intermediate result. ;
* The join should return 1 row. ;
proc cas;
fedsql.execdirect query="
select
*
from
v, (select distinct * from x) x
where
v.x = x.x";
quit;
* The join should return 1 row. ;
proc cas;
fedsql.execdirect query="
select
*
from
v, (select distinct * from x) x
where
v.x = x.x";
quit;
